Polymarket Predicts 72% Chance Supreme Court Will Rule Trump Tariffs Illegal

The statement is strongly supported by multiple high-authority and primary sources. Two separate articles from Barron's, a reputable financial news source, directly cite the Polymarket prediction. One states the administration's odds of success are 27%, which equates to a 73% probability of the tariffs being ruled against (illegal). The other article explicitly states Polymarket puts 76% odds on the court ruling against the tariffs. Furthermore, a user profile page on the Polymarket platform itself shows a trade on the relevant market where the "No" option (meaning the court will not rule in favor of the tariffs) is priced at 73¢, directly corresponding to a 73% probability. While the numbers cited vary slightly (73% and 76%), they are all very close to the 72% in the statement. This slight variation is expected for a dynamic prediction market where odds fluctuate. The consistency across these reliable sources provides strong evidence that Polymarket indicated a probability in this specific range. The only irrelevant source was a Yahoo Finance article that did not mention prediction markets. The evidence overwhelmingly corroborates the claim.
